[求助] 关于在表达蛋白和GFP蛋白之间的linker

各位好,我最近在做膜蛋白的表达,在构建载体的时候我在膜蛋白的C端还加了GFP指示蛋白,但是在诱导表达后,根本看不到菌发出绿色荧光,而我只表达GFP时却能看到菌是绿色的,我在构建载体的时把膜蛋白和GFP直接连在一起了,中间没有加linker regions,我想问一下各位,我的菌株看不出绿色的原因是不是我没有加一个linker的原因呢,如果有做过这方面的大侠是不是可以知道一下我呢,多谢各位!

protein of interest surely weakens fluorescence of GFP with linker or without linker.
i have ever made experiment about expression of fusion protein including GFP,
the fusion protein including GFP can emit green fluorescence although its green fluorescence is weaker than that of control.
but the fusion protein in my experiment is located at the cytoplasm, and your protein occured in the membrane, I don`t know whether location of protein including GFP effects fluorescence emission or not.

Thank you very much for your advice, but there is a question, when you express fusion protein including GFP,  can you watch the green fluorescence with the naked eye ?

no,I can`t.
even green fluorescence wasn`t seen in the control group(only GFP) by naked eyes.
